- Page 2 CIRCUIT DESCRIPTION INPUT STAGES The balanced input stages of the L200 Line Amplifier utilize a FET input LF347 quad opamp in a clean, quiet inverting instrumentation amplifier configuration. Input levels up to +24dBm will be handled without clipping, excess levels cause only clean clipping without hang-up or phase reversal.
- Page 3 -10dBu nominal unbalanced signal. POWER SUPPLY The L200 requires 22 to 30VDC and are designed to share a common external 24VDC "Wall Wart" type power supply. A pair of loop-thru DC connectors on the rear of each module permit several units to be daisy-chained with P/N20602-1 DC power cables to a single power supply.
- Page 4 MOUNTING Single desk mounting kits consist of a pair of angled base plates that mount under the lower front and rear cover screws of a single unit, to raise and to tilt it for easy use. In addition, one or more sets of vertical stacking plates, mounting to the upper front and rear cover screws of the bottom unit, allow multiple units to be stacked.
